Step-by-step explanation:
Given:
A semicircle.
To find:
Arc length of the semicircle = ?
Solution:
Formula for angle subtended by an arc on the center of circle is given as:

where
is the arc length and
is the radius of semicircle.
Angle of full circle is 
So, angle of semicircle = 
Using the formula, we can see that:


So, the answer is:
Arc Length of semicircle =
